摘要
通过对国内外水泥混凝土桥面沥青铺装层技术领域研究现状和发展趋势的分析与总结,研究了不同国家的混凝土桥梁类型及交通荷载环境对沥青铺装层技术的影响,针对沥青铺装层病害机理及分类方法、铺装层结构组合、铺装层材料、铺装层结构设计等进行了详细剖析。分析结果表明:铺装层的耐久性不完全取决于本身强度或材料的卓越性,更取决于铺装层结构、材料与桥梁结构、混凝土桥面的适应性;铺装层及防水粘结层的综合设计、施工质量控制及评价方法是保障其耐久性的关键;降噪、融冰雪、易再生等绿色铺装材料值得提倡,沥青铺装层施工质量控制体系亟待于建立和完善,更宜人性化选择的沥青铺装系典型结构值得研究。
Through the analysis and summary on domestic and abroad research statuses and development trends of asphalt pavement technology on cement concrete bridge deck, the influences of concrete bridge types in different countries and traffic load circumstances on asphalt pavement technology were studied, especially on the mechanism of asphalt pavement diseases and the classification method, pavement structure combination, pavement material and pavement structure design. Analysis result shows that the durability of asphalt pavement is not entirely determined by the strength or excellence of pavement material, but more by the adaptabilities of pavement structure and material to bridge structure and concrete bridge deck. Integrated design of pavement and waterproof, construction quality control and evaluation methods are the keys to ensure the durability of pavement. The green materials of pavement for noise reduction, ice and snow melting, and easy regeneration are worth advocating. Asphalt pavement construction quality control system should be established and improved. Asphalt pavement typical structure with high humanization is worth studying. 4 figs, 43 refs.
